Animate a Variable

Animate a Variable

Top 

You can also animate the drawing. To do so, we can set start and stop values for the variable t.

  1. In the Variables list, select t.
  2. The first input field below the video playback interface specifies the start value. Enter 1.5.
  3. The middle field specifies the number of seconds to pause between animation steps. Accept the default value of 4. The input field to its right specifies the stop value. Enter 12.

Tutorial 2 (animate t) 

  1. To animate the drawing, click Play button (Tutorial 2 (Play button) ).

NOTE: The start and stop values that yield an interesting animation depend to some extent on where youve located objects in your drawing. Experiment to find values that make an interesting animation. Values that do not allow GE to create a construction sequence will cause objects to disappear briefly. Theyll reappear when values make sense again, or when the animation stops.
